Is there a formula I can use in Excel to determine the usable space that I'll achieve with various hard drive sizes, raid configs, stripe size, filesystem type, and allocation/cluster sizes and virtual files.
For example, trying to figure out how much usable space I'll have without having to buy the system of the following:
8 x 600GB SAS drives
Stripe Size 64K (RAID)
Windows allocation/cluster size: 64K
Then creating a 200GB hyper-v disk file on that volume.
And then figure out the same for 2 x 2TB drives, or with different RAID types/configs.
